APPARATUS roe HACKLING Ann sritnan-mernnx AND ornnniiono-srnrtn FIBERS.

To all whom it may concern Be it known that I, JOSHUA VAnnNTnvE Evns, a British subject, residing atBelfast,

county Antrim, Ireland, have invented cer tain new and usefullmprovements in Apparatus for Hackling and Spreading Flax and other Long-Staple Fibers, of which the following is a specification.

This invention relatesito apparatus by which the stricks or pieces of hackled flax are transferred from the holdersof a hackling' machine and deliveredto a spread board or other machinesuch as'describ ed in U. S. Letters Patent No. 1,099,084,: granted June 2, 1914:, to myself and Peter Shaw.

[The objects of the present "improvements areto simplify the machine anf'clreduce its.

parts primarily with the view of restricting the movement of the grippers wh-ichwith draw the flfax from the holders by soflplacw ing them that the flax will 'slidelvertically into the space between the two jaws and also to improve the machineintrespect ofother details of construction. 1

i The invention will bedescribed with ref-' arms "(Z cl so arranged that when at rest to erence to the accompanying drawings.

The apparatus may be mounted on a separate-framing; or ,itfmay. be mounted on the framing ofa spread board, gill frame, or other 'machine to; which the flax is to be transferred or it may be mounted on the frame of the hackling machine from which the flax is taken. 1 i w The hackling machines, the cross channel B betweentwohackling machines and the holder. 6 which carries the strick or piece of flax under operation are of the ordinary .construotion for the well known automatic hackling' machines. T

The transferrer apparatus comprise two.

swinging or pendulous memberspivoted to a suitable frame or bracket and operated by.

cams to grip the piece-of flax m and draw it forward out of the holder 6 and transfer the flax to andlay it upon the next machine by which it is treated.

,The grippers of the transferorspreading apparatus are formed of two bars or jaws D and 1) .flat or curved mounted on pendulum receive the flax a? space lies between the aws into-which the-depending ends of the flax '00 can move uninterruptedly as the holderb is traversed alongthe cross channel B. j The j aw. or bar D is caused to close upon the jawfDitog-rip'the flaxby a sliding or rotary gmovement .and a rotary movement 1s imparted to the two jaws simultaneously in a direction away from the holder 6 to draw the flaxm therefrom andigdeliver it to the desired position. .T-he gripperjaw or bar Dygand thesupporting arms .(Z d are carried on sleeve Z fixed itothe frame at one side ofthe machine. *The gripper bar1 or jaw D is also mounted upon the radial supporting arms. d d and is-capable of sliding to. and; fro, arod d? therefrom extending to a cam (Z, mountedon the shaft-a} by which ,thejaw: D, is moved into. contact withv the. jaw or,

barDt and moved (in thegreverse direction by a spring .cZi. Atoothed wheel or pinion shaft d? to closeithe j aw .1) upon the jaw. D to igrip the' flax. by a suitably designed cam oreccentric A through a lever a connecting: e i ails l v m a id'a w rcl e fi ing movement is imparted to the quadrant 0 by the cam A through the lever a and connecting rod a to give the rotary movement to the grippers D D to withdraw the flax 00 from the holder 6 and deliver it where desired. The grippers are opened to release may hang freely or may be provided with runners e to traverse a guide rail or bracket 6.

The grippers D D may deliver the flax w to nippers G, F, (such as in Figs. 12 and 13) or direct onto the lattice II of a spreadboard or other machine, or onto the fallers K (such as in Fig. 14) of a gill-frame or other machine. v

In the arrangement shown 1n Figs. 4: and

.5 the transfer or spreading apparatus is similar to that described and mounted on the end of an upright rocking lever D pivoted to the machine frame and operated by the cam A to give a rectilinear move- V ment to the jaws D D as they recede from and approach to the flax holders 6, the forward and backward path being shown in dotted lines. 7

In the arrangement shown in Fig. .6 the pendulum arms of the transfer or spreading apparatus are mounted on a bell crank lever or wrist plate D to give the rectilinear movement to the jaws D D the bell crank being operated by a similar cam as shown in Fig. 4 and the pinion 0 operated by a rack a sliding in a shoe 0.

In the arrangement shown in Figs. 7 to 11 the gripper bars D D are similarly mounted on the pendulum arms 03 d to re ceive the piece of flax w. The'gripper'jaw or bar D and its pendulum arm at are carried on a stud or pin 01 by links 0 suspended from a transverse shaft C and the gripper jaw or bar D with its supporting arm a? is carried on a pin or stud 0Z journaled in bearings in the frame of the machine. Upon one end of the shaft C a toothed quadrant 0 is afiixed and to the arm 03 a pinion c is connected which gears with the toothed quadrant. A connecting rod a is connected to the links 0 and a connecting rod a to the quadrant 0. A rocking or swinging movement is imparted to the links 0 by a cam A through the lever a and connecting rod 0; to close the jaw D upon the jaw D to grip the flax a and to bring the stud or pin 03 into alinement withthe stud of the grippers or pin (Z and thereafter a rocking or oscillating movement is imparted to the quadrant c by the cam A through the lever 64 and connecting rod 0, to give the rotary movement to the grippers D D to withdraw the flax a from the holder 6 and deliver it where required. The grippers D D are opened to release the flax at the end-of the traverse by the-cam A and the grippers are returned to their first position by the cam A. The grippers are preferably counter balanced by a weight IV. To the gripper bar or jaw D an apron of sheet metal or other material may behinged to support or carry forward the depending end of the flax w. The apron E may hang freely or may be provided with runners e to traverse a guide rail or bracket 6. The grippers D D may deliver the flax w to nippers G, F

(such as in Figs. 12 and 13 or direct onto' the lattice H of a spreadboard or other machine or onto the fallers K (such as in Fig. 14) of a spreadboardor other machine.

In the arrangement shown in Fig. 10 the gripper bar D is-carried by the pendulum arm or frame (Z mounted on the rocking shaft (Z raised and lowered-by a quadrant or otherwise in the manner hereinbefore described. The gripper bar D 1S carried by an arm or arms (Z on a rocking shaft or stud cl carried in brackets on the pendulum arm or frame (Z! A spring (i acting against an extension (Z of the arm a? forces the gripper bar D against the gripper barD when'the flax is between them the spring al 'being supported by a rod pivoted to an extension (l -of the pendulum arm or frame A lever (3 is aiiixed to the rocking shaft (Wand a bell crank lever [Z pivoted on a studon the frame of the machine engages therewith to open the grippers to receive the flax when the pendulum arm is in the position'shown. The lever (Z isoperatedby a connecting rod (Z and a cam (not shown). A stationary cam surface (Z is bolted to the framing in the path of the'lever cZ and when the pendulum arm and grippers swing to transfer the flax from the holder 7) the lever d engages therewith opening the grippers 'to release the 'flaX. f V

Where the grippers D D deliver or lay the flax upon the lattice. H of the spread board as in Figs. 1 to 9 a rocking arm I-I carrying the roller h is employed to nip the flaxagainst the traveling lattice H and retain it upon the lattice as the grippers D-D' open and pass forward leaving the fiaxbe hind upon the lattice. V I

Where the grippers D D deliver the flax onto the fallers K of the spreadboard or other machine as in Fig. 14, the bed of fall- 7 In the arrangement in Fig. 15 the appa-- A. H... .i

ratus is carried by an extension H of the framing of the spreadboard instead of on a separate or independent framing the jaws D D being operated by the cams A and A and connecting rods a a as described with reference to Figs. 1, 2 and 3. i

In the arrangement in Figs. *16 and 17 the apparatus is carried by an overhanging to protect by Letters Patent is I 1.
